If you keep this to European military spending, and "fair share" in NATO, over-reliance on USA for security - then yes - though it's worth noting that that's been US policy (as well as domestic policy for European nations) for Reagan, Bush Snr, Clinton, Bush Jr, Obama and Biden. America wanted a Europe that was beholden to the US. Only Trump made an issue of this, and even he wants Europe to be beholden to America - he just hasn't joined the dots.
However, if you look at this as a negotiation for peace in Ukraine, then Europe as a block is a more-than-equal partner here. Europe as a block (and IIRC the EU as a block) has done more to support Ukraine than the USA has - okay, each nation individually has done less, because all are significantly smaller with smaller economies and massively smaller militaries (see above). Furthermore, this war is taking place on European soil - it's our front door that's being shat on, with specific and explicit threats that EU members are "next". If that doesn't "entitle" the EU to a seat at the table, then I really don't know what does.
